Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot water storage tanks, specifically to steam-heated water tanks. Background Technology
[0002] The hot water tank in the ultrapure ammonia workshop uses a direct steam flow method for heating, where steam flows directly upwards through the hot water. This method generates high steam pressure, impacting the tank and causing significant vibration. Furthermore, the direct steam flow results in a small effective contact area and poor heat exchange, leading to uneven temperature distribution in the hot water tank. Consequently, the outlet temperature of the hot water pump connected to the tank is unstable. The hot water pump also tends to draw in excessively hot water, causing temperature fluctuations in the production process. Therefore, the technical problem this application aims to solve is: how to improve the uniformity of water temperature in the steam hot water tank. Utility Model Content
[0003] To address the aforementioned technical problems, this invention proposes a steam-heated water tank. This solution utilizes a mixer to thoroughly mix steam and water, thereby improving the heat exchange efficiency of steam and water. Compared to existing technologies that use straight-through pipes for steam supply, this solution produces smaller bubbles and a larger water-steam heat exchange surface, thus improving both heat exchange efficiency and the uniformity of water temperature within the tank.

Detailed Implementation
[0028] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.
[0029] like Figures 1 to 7 As shown, this embodiment proposes a steam-heated water tank, comprising:
[0030] The cylinder 11 has an inlet 12 at its upper end and an outlet 13 at its lower end.
[0031] Steam inlet pipe 14 is installed on the cylinder 11, and the lower end of the steam inlet pipe 14 extends to the lower end of the inner cavity of the cylinder 11.
[0032] Mixer 15 is connected to the lower end of steam inlet pipe 14 via a branch pipe;
[0033] Vent pipe 16 is installed at the top of cylinder 11 to stabilize the air pressure inside cylinder 11.
[0034] The technical advantages of this solution are as follows: By incorporating a mixer 15 to thoroughly mix steam and water, the heat exchange efficiency of steam and water is improved. Compared to the existing technology that uses a straight-through pipe for steam supply, this solution produces smaller bubbles and a larger water-steam heat exchange surface, thereby improving both heat exchange efficiency and the uniformity of water temperature within the cylinder 11.
[0035] In one embodiment of this invention, an overflow port 17 is provided at the upper end of the cylinder 11 to prevent the liquid level inside the cylinder 11 from becoming too high.
[0036] In one embodiment of this invention, a drain port 18 is provided at the lower end of the cylinder 11. The drain port 18 facilitates the periodic cleaning of contaminants inside the cylinder 11.
[0037] In one embodiment of this invention, the top of the cylinder 11 is provided with a light-transmitting opening 19. When the cylinder 11 needs to be cleaned, the inner cavity of the cylinder 11 is cleaned and ventilated through the light-transmitting opening 19.
[0038] In one embodiment of this invention, a manhole 20 is provided on the side wall of the cylinder 11. This manhole is used for inspecting and repairing the components inside the cylinder 11.
[0039] In one embodiment of this invention, the cylinder 11 is provided with a level gauge port 21. There are two level gauge ports 21, one for installing a high level gauge and the other for installing a low level gauge.
[0040] In one embodiment of this invention, the cylinder 11 is provided with a thermometer port 22 for mounting a thermometer to detect the water temperature inside the cylinder 11.
[0041] In one embodiment of this invention, the mixer 15 is provided with a sealed chamber 23. The upper end face of the mixer 15 is provided with a connecting pipe 25 that communicates with the sealed chamber 23, and the lower end face of the mixer 15 is provided with a nozzle 24 that communicates with the sealed chamber 23. High-temperature steam from outside is introduced into the mixer 15 through a steam inlet pipe 14. The steam in the sealed chamber 23 enters the water at high speed downwards through the nozzle 24, thus forming a water-vapor mixture.
[0042] The connecting pipe 25 and the branch pipe at the lower end of the steam inlet pipe 14 are connected by a flange.
[0043] As one embodiment of this invention, a drain pipe 26 is installed on the mixer 15, and the drain pipe 26 penetrates the upper end face and the lower end face of the mixer 15.
[0044] As steam flows rapidly downwards through nozzle 24, water and air currents form near nozzle 24, causing a pressure drop in the vicinity. Meanwhile, water above the guide pipe 26 flows downwards along the guide pipe 26, further mixing with the steam. This effectively improves the mixing efficiency of water and steam.
[0045] In one embodiment of this invention, two baffles 27 are vertically mounted on the lower end face of the mixer 15, with the nozzle 24 and the guide pipe 26 located between the two baffles 27. The baffles 27 are configured to guide the water flow and airflow below the nozzle 24, preventing the steam coil from moving upwards while adhering to the surface of the cylinder 11, thereby increasing the travel distance of the water flow and airflow.
[0046] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
